.SH DESCRIPTION
.sp
.LP
Services form the middle layer of the Service Configuration Facility repository
tree. Services are children of a scope (see \fBscf_scope_create\fR(3SCF)) and
have three sets of children:
.sp
.ne 2
.na
\fBProperty groups\fR
.ad
.RS 19n
These hold configuration information shared by all of the instances of the
service. See \fBscf_pg_create\fR(3SCF), \fBscf_iter_service_pgs\fR(3SCF), and
\fBscf_iter_service_pgs_typed\fR(3SCF).
.RE

.sp
.ne 2
.na
\fBInstances\fR
.ad
.RS 19n
A particular instantiation of the service. See \fBscf_instance_create\fR(3SCF).
.RE

.sp
.LP
A service groups one or more related instances and provides a shared
configuration for them.
.sp
.LP
An \fBscf_service_t\fR is an opaque handle that can be set to a single service
at any given time. The \fBscf_service_create()\fR function allocates and
initializes a new \fBscf_service_t\fR bound to \fIhandle\fR. The
\fBscf_service_destroy()\fR function destroys and frees svc.
.sp
.LP
The \fBscf_service_handle()\fR function retrieves the handle to which \fIsvc\fR
is bound.
.sp
.LP
The \fBscf_service_get_parent()\fR function sets \fIsc\fR to the scope that is
the parent of \fIsvc\fR.
.sp
.LP
The \fBscf_service_get_name()\fR function retrieves the name of the service to
which \fIsvc\fR is set.
.sp
.LP
The \fBscf_scope_get_service()\fR function sets \fIsvc\fR to the service
specified by \fIname\fR in the scope specified by \fIsc\fR.
.sp
.LP
The \fBscf_scope_add_service()\fR function sets \fIsvc\fR to a new service
specified by \fIname\fR in the scope specified by \fIsc\fR.
.sp
.LP
The \fBscf_service_delete()\fR function deletes the service to which \fIsvc\fR
is set, as well as all of its children.
.SH RETURN VALUES
.sp
.LP
Upon successful completion, \fBscf_service_create()\fR returns a new
\fBscf_service_t\fR. Otherwise, it returns \fINULL\fR.
.sp
.LP
Upon successful completion, \fBscf_service_handle()\fR returns the handle to
which svc is bound. Otherwise, it returns \fINULL\fR.
.sp
.LP
Upon successful completion, \fBscf_service_get_name()\fR returns the length of
the string written, not including the terminating null byte. Otherwise, it
returns -1.
.sp
.LP
Upon successful completion, \fBscf_service_get_parent()\fR,
\fBscf_scope_get_service()\fR, \fBscf_scope_add_service()\fR, and
\fBscf_service_delete()\fR return 0. Otherwise, it returns -1.
